1. A preparation method for starch-embedded aroma substance microcapsule, characterized in that, it comprises the following steps:

(1) performing degreasing treatment on starch;

(2) high-temperature treatment: dispersing the degreased starch in the step (1) into distilled water to formulate a starch slurry in a range of 5%˜15%, and treating at high temperature of 120˜180° C. for 40˜60 min, then cooling to 50˜100° C. to obtain a starch paste; and

(3) preparation for microcapsule: firstly dispersing an aroma substance with larger molecular cross-sectional area in the starch paste in the step (2), stirring and complexing at 50˜90° C. for 20˜40 min, adding an aroma substance with smaller molecular cross-sectional area, continuing stirring and complexing for 20˜40 min, then naturally cooling, standing still, centrifuging, washing, and drying, to obtain a white powdered product which is the starch-embedded aroma substance microcapsule.
